Your thermostat is probably stuck open. Replace it with an OEM Motorcraft version, not aftermarket.
Pros: OEM Motorcraft version
Cons: not aftermarket
Duralast is ok. Does not have to be OEM. It will work just as good

I used a motorcraft RT-1139 thermostat. Comes with a jiggle valve to help bleed air already installed and cost me 8 bucks. You won’t find any place that says they fit other than some forum posts but they do indeed work, I installed one on my MJ with the only issue being me not refilling the radiator after dumping all the coolant.
Pros: works well, jiggle valve, good value
Vehicle:
Jeep
Part number: RT-1139
I requested they use only Motorcraft thermostat, because I knew there was a part # update. Threw the updated Motorcraft one in and it solved the issue.
Pros: solved issue, updated part
Vehicle:
Ford
I replaced the thermostat from a non-OEM to Motorcraft about a month ago, and the only difference has been the speed at which the dial moves from higher temps to its normal positon.
Pros: faster dial movement
